Air quality measurements-From rubber bands to tapping the rainbow.

Unlabelled: It is axiomatic that good measurements are integral to good public policy for environmental protection. The generalized term for "measurements" includes sampling and quantitation, data integrity, documentation, network design, sponsorship, operations, archiving, and accessing for applications. Each of these components has evolved and advanced over the last 200 years as knowledge of atmospheric chemistry and physics has matured.

Analysis of a summertime PM2.5 and haze episode in the mid-Atlantic region.

Observations of the mass and chemical composition of particles less than 2.5 microm in aerodynamic diameter (PM2.5), light extinction, and meteorology in the urban Baltimore-Washington corridor during July 1999 and July 2000 are presented and analyzed to study summertime haze formation in the mid-Atlantic region.

Protein synthesis of eucaryotic cells could be decreased by antisense-DNA of the multi KH domain protein vigilin.

Vigilin, a member of the KH protein family, is exceptional among these proteins as it contains 14 KH domains in consecutive order. Vigilin is present in the nucleus and the cytoplasm of all eucaryotic cells studied so far and has apparently high affinity to tRNA and mRNA. There is circumstantial evidence that vigilin expression parallels high translational activity as demonstrated for pancreatic cells in vitro and in vivo as well as for carcinoma cell lines.
